Directions

Whip the cream in a bowl using a whisk or hand mixer. Just before soft peaks are formed, add the confectioners' sugar and lime zest. Whip to soft peaks.

Remove the pound cakes from the freezer and cut each in half vertically with a serrated knife. Then cut each of the halves horizontally. Cut rounds out of each block of cake using a 3-inch cutter. Then cut each round in half horizontally, so you're left with 16 equal-sized rounds.
